As of 4.0.3 she can be found at Galen's Fall at the edge of Arathi Highlands, next to Thoradin's Wall.

She seems to give a subtle hint towards a possible future event in Arathi Highlands upon completing the quest chains available to you at Galen's Fall.

You have served us well here, <name>. Now that we've made our mark, the next phase of our conquest will occur over months rather than minutes.

There is much work yet to be done, and I will spare you the tedium of waiting for our fortifications to trickle in. Travel to the east, to Hammerfall. The orcs there will no doubt have use of your aid.
